Effective immune booster
4 people found this helpful
Excellent vitamin C. I highly recommend it. I don't take it regularly, but when I feel unwell, I take four pills a day for a few days, and it works wonders. It helps me recover faster even when I'm already ill. I use it sparingly, so it should last a while, but I will order more soon.

Improved immunity
4 people found this helpful
Ester-C with citrus bioflavonoids, along with Lysine, really helps with herpes! This form of vitamin C is retained in the body longer, making it effective. I used it daily for genital herpes and noticed fewer rashes that heal faster. Since taking it, my immunity has improved noticeably—I didn’t get ill during recent flu seasons. I will continue ordering it as the reviews were really helpful.

Skin improvement

For me, Ester-C remains the most effective vitamin C. I take it mainly for my skin, which has improved dramatically over the past two years. I have struggled with problematic skin and noticed results just a week and a half after starting. It boosts my immune system as well, so it's a win-win.

The quality of this vitamin is excellent. My family and friends have ordered it for years, and I appreciate the convenient dosage and price. The addition of citrus flavonoids enhances absorption, making this effective and essential for those with autoimmune disorders.

Recommended for safety
I have been taking Ester-C 500 mg for a year on my doctor's advice for my autoimmune disorder. This form is safe for my stomach and has antioxidant qualities. I now take it twice daily after meals and find it easy to swallow. I also give it to my children.

Suitable for symptoms

This vitamin is suitable for me due to my stomach issues; it’s mild and has no side effects. It helps swiftly at the first signs of discomfort. My daughter uses it for her skin and is pleased. We will reorder and I recommend it.

Health maintenance
1 people found this helpful
I've been taking vitamin C for a month—one capsule daily, and two if I feel unwell. It seems to help avoid illness, especially as colleagues got sick with coronavirus, and I didn’t. I will continue this regimen alongside my omega supplements and have now ordered zinc and vitamin D as well.

Increased acidity issues
2 people found this helpful
I initially took Ester-C and had no issues, but this time it increased my stomach acidity and created a burning sensation in my mouth. While convenient to take, I felt it wasn't well-absorbed. I had to be cautious about combining it with other vitamins due to potential allergic reactions.
